Part Number: TPD2S300
In the data sheet it states :-
If desiring to power the CC/PD controller during dead battery mode and if the CC/PD Controller is configured as a DRP, it is critical that the TPD2S300 be powered before or at the same time that the CC/PD controller ispowered. It is also critical that when unpowered, the CC/PD controller also expose its dead battery resistors.When the TPD2S300 gets powered, it exposes the CC pins of the CC/PD controller within 200 μs. Once theTPD2S300 turns on, the RD pull-down resistors of the CC/PD controller must be present immediately, in order toguarantee the power adaptor connected to power the dead battery device keeps its VBUS turned on. If the poweradaptor sees the CC voltage go high to the SRC.Open region, it can disconnect VBUS. This removes power fromthe device with its battery still not sufficiently charged, which consequently removes power from the CC/PDcontroller and the TPD2S300. Then the RD resistors of the TPD2S300 are exposed again and connect the poweradaptor's VBUS to start the cycle over. This creates an infinite loop, never or very slowly charging the mobiledevice.
Is there any such requirements when the CC Controller is configured as a UFP ???
